Career
In 2004, N'Dou was forced into early retirement when he collapsed after a loss to Isaac Hlatshwayo. A subsequent brain scan revealed an abnormality that would have endangered N'dou's health at the time if he continued to box. However, he returned to the ring in 2009.
Coincidentally, Ndou had competed in the same featherweight boxing tournament as Mayweather at the 1996 Summer Olympics. After defeating Casey Patton of Canada in a controversial referee stoppage, N'dou lost in the second round to the eventual gold medallist, Kamsing Somluck of Thailand. He then fought on 29 January 2011, defeating Welcome Ntshingila by unanimous decision in a ten-round bout.
